9/10 is about 10/10 or 1 and 1/3 is about 0, so just add 1+0=0. Annie walked 1 mile yesterday.
Hope that helped:D
D=dog's weight
c=cat's weight
d=7c
d+c=72
sub 7c for d
7c+c=72
8c=72
divide both sides by 8
c=9
d=7c
d=7(9)
d=63
dog=63lb
Answer:
Explanation:
Method 1
First, list the multiples of both numbers:

To find the lowest common multiple (LCM) of 6 and 8, first express the numbers as a product of its prime factors.

Next, pick the highest powers for each of the numbers:
Answer:
Step-by-step explanation:
If you want to make

into a perfect square binomial, take half the linear term, square it, then add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36.
The value that makes this a perfect square binomial is 36.
Writing the expression as a square of the binomial is:

So, first let's refill the barrel to the top:
37.5 + 7*2.5 = 55
Now that it's full again, let's divide the total amount by the rate of water loss:
55/2.5 = 22
It will take 22 minutes to completely empty the rain barrel
